Her books - The Other Side and its sequel The Bright Side - raised money towards the cause.

She also took part in a series of fundraisers, including a skydive, swimming the length of the English Channel, the Leeds 10K run and a 13-mile trek in the Lake District.

Mr Pointon, 40, also completed the 96-mile West Highland Way and took on a gruelling trek on the Great Wall of China for the charity.

Dr Granger’s #HelloMyNameIs campaign for more personalised and compassionate care has been supported all over the world and 400,000 health workers across 90 organisations had backed drive by the time she died.

She was awarded an MBE and recognised with a Special Achievement Award from the BMJ.

Mr Pointon, who lives in Mirfield, said: "There has been huge support for Kate and that campaign and we'll make sure it continues.

"There's a few things going on across all parts of the world on the day.

"We will get the campaign trending on Twitter again across the world and there will be photos of the campaign on social media."

Various NHS trusts will be re-launching Dr Granger's campaign as part of the international day.

Around 14,000 members of staff at Leeds' hospitals have signed up to the campaign.

"We do this with pride and affection. We will be thinking of Kate and how she helped us all to realise how often little things like using our first name can mean so much to patients and their families.”

Staff who pledge support for the campaign are given a special #HelloMyNameIs name badge by the trust to wear.

In October, Mr Pointon said he is taking a career break from his job, as a supply chain manager at Asda in Leeds, to travel the world and spread the campaign to a series of countries.

He said the company had been "amazingly supportive" as he prepares to lead various talks at conferences during the 10-month international tour.
